Just Is

I know it's a long shot but I need a S55 oil pump for my engine swap. Putting a 2003 n/a 5.4 in my 2001 clk430. Due to differing oil pumps and oil pans, i have to make a hybrid pump and the S55 is the answer according to Blackbenzzz. Must be from a cl55 or s55 between 2003 and 2006.

Anyone know where I can find one? My dealer says there aren't any in the states and they "can't order one."
